TREATISE ON MILCH COWS. 59 



CLASS II. 



Cotrj. 



The shape of the escutcheon of this Class is very different from that of th.2 

 First. The upper part of this escutcheon consists, as is seen in the Drawing, 

 (Plate II.) of a growth of ascending hair, rising vertically, and without any inter 

 ruption from descending hair, to the vulva. Its resemblance to the list or selvage 

 of a piece of cloth is what suggested the name that I have given to this Class. 



HIGH COW, 



FIRST ORDER. Cows of this Order yield, during the hight of their flow, eighteen 

 litres a day, and continue to give milk until they are eight months gone with 

 calf. Like those of the First Order of the First Class, they never go dry, if we 

 j choose to milk them all the time. 



The udder is delicate and covered with a fine, downy hair, growing upward. 

 The escutcheon consists of a growth of ascending hair, commencing between the 

 fore teats, and also on the inner surface of the thighs just above the hock joint. 

 It expands as it extends upward, till it reaches the points A A. Here it is bound 

 ed by a right line, which runs across the inner side of the thigh, from A A to 

 the points D D, which are about four inches distant from each other. From these 

 points right lines rise vertically to the vulva, where they terminate, about an inch 

 and a half apart. 



Above the two hind teats, and nearly in a vertical line with them, are two oval 

 marks (E E), formed by a growth of descending hair, distinguishable by its lus 

 tre, the size of which is about the same as in the Flanders Cow. 



In these Cows, also, the skin of the inner surface of the thighs is of a yellowish 

 color. 



SECOND ORDER. These Cows yield, while at the hight of their flow, sixteen 

 litres a day, and continue to give milk until seven and a half months gone with 

 calf. 



The escutcheon is the same as that of the First Order, only the points A A are 

 not so high up, and the entire figure is on a rather smaller scale. To the left of 

 the vulva, outside of the escutcheon, is a small streak of ascending hair (E), about 

 two and three-fourths inches long by less than half an inch wide. There is but 

 one oval above the hind teats, on the left side. The entire escutcheon is distin 

 guishable by the hair within being more glossy than that around it. 



THIRD ORDER. These Cows yield, while at the hight of their flow, fourteen 

 litres a day, and they continue to give milk until they are six months gone with 

 calf. 



The escutcheon differs from the preceding m the following particulars : it is on 

 a smaller scale ; the points A A are nearer to the points D D, and the lines which 

 rise from the latter points meet at the vulva, so as to form an acute angle. On 

 each side of the vulva is a streak of ascending hair (F F,) of the same size as the 

 one in the preceding order ; that on the right being, however, sensibly shorter 

 , than the one on the left. There is, also, but one of the oval marks (E) above the 

 teats, to the left. 



FOURTH ORDER. These Cows yield, while at the hight of their flow, twelve \ 



litres a day, and continue to give milk until they are four and a half months &amp;lt; 



: gone with calf. f
